AI Article Synopsis

  • Topical drug administration offers fewer side effects and improved therapeutic effects compared to oral methods.
  • The study used etodolac (ETD), an NSAID from the BCS class II, incorporating it into nanostructured lipid carriers (NLC) and testing various gel formulations for properties like pH and viscosity.
  • Results showed that all gels had a pH below 7 and exhibited non-Newtonian behavior, with the NLC formulation in Carbopol demonstrating the quickest drug release and permeation, showcasing effective stability and pharmaceutical benefits.

Article Abstract

Topical administration of drug is an attractive alternative to the oral administration as it provides a reduction in adverse reactions and an enhancement of therapeutic effects. The use of lipid carriers in hydrogel structures makes it possible to introduce lipophilic substances in a dissolved form. In this study, an NSAID from the BCS class II, etodolac (ETD), was used. The nanostructured lipid carriers (NLC) obtained with ETD were incorporated into semi-solid forms (gels). Hydrogels with the suspended drug and oleogel were also prepared for comparison purposes. The obtained gels were tested in terms of pH, viscosity, rheological, mechanical, and bioadhesive properties. The release and permeation through membranes were also studied. All tested formulations were characterized by a pH below 7, which ensured the physiological state of the skin. The viscosities of all gels decreased with increasing shear rate, indicating non-Newtonian behavior. The fastest ETD release was observed for NLC with a Carbopol base (formulation F1); a similar result was noticed in the permeation test. The developed gel formulations containing ETD-NLC dispersion and Carbopol or Poloxamer as gelling agents were stable and possessed beneficial pharmaceutical properties.

Background: Tavaborole (TAV), a benzoxaborole derivative, is an FDA-approved antifungal agent for treating onychomycosis, a common and persistent fungal infection of the toenails.

Objective: This study aimed to develop a robust stability-indicating HPTLC method to determine TAV in nanostructured lipid carriers (NLC) using a comprehensive approach that includes risk assessment, and Analytical Quality by Design.

Methods: The critical method parameters influencing the HPTLC results were screened using a Placket-Burman screening design followed by its optimization using a central composite optimization design.

Background: A recent case report described an individual who was a homozygous carrier of the APOE3 Christchurch (APOE3ch) mutation and resistant to autosomal dominant Alzheimer's Disease (AD) caused by a PSEN1-E280A mutation. Whether APOE3ch contributed to the protective effect remains unclear.

Method: We generated a humanized APOE3ch knock-in mouse and crossed it to an amyloid-β (Aβ) plaque-depositing model.

Background: Apolipoprotein E (ApoE) exists in three protein isoforms: E2, E3, and E4, which differ by only one or two amino acids. These slight differences profoundly effect protein structure and function, allowing each isoform to differentially impact Alzheimer's Disease (AD) risk. Relative to the most common E3 isoform, E4 dramatically increases risk, while E2 confers a substantial decrease in risk.

Background: The Apolipoprotein E ε4 (APOE-ε4) allele is common in the population, but acts as the strongest genetic risk factor for late-onset Alzheimer's disease (AD). Despite the strength of the association, there is notable heterogeneity in the population including a strong modifying effect of genetic ancestry, with the APOE-ε4 allele showing a stronger association among individuals of European ancestry (EUR) compared to individuals of African ancestry (AFR). Given this heterogeneity, we sought to identify genetic modifiers of APOE-ε4 related to cognitive decline leveraging APOE-ε4 stratified and interaction genome-wide association analyses (GWAS).

Background: APOE*4 is the strongest genetic risk for late-onset Alzheimer's disease (AD), but other genetic loci may counter its detrimental effect, providing therapeutic avenues. Expanding beyond non-Hispanic White subjects, we sought to additionally leverage genetic data from non-Hispanic and Hispanic subjects of admixed African ancestry to perform trans-ancestry APOE*4-stratified GWAS, anticipating that allele frequency differences across populations would boost power for gene discovery.

Method: Participants were ages 60+, of European (EU; ≥75%) or admixed African (AFR; ≥25%) ancestry, and diagnosed as cases or controls.
